Results: Geographic faunal provinces and ecoregions were the strongest predictors
of coral resistance to thermal stress, with sites in the Australian, Indonesian and
Fiji-Caroline Islands coral provinces having higher resistance to thermal stress than
Africa-India and Japan-Vietnam provinces. Ecoregions also showed strong gradients
in resistance with highest resistance to thermal stress in the western Pacific and Coral
Triangle and lower resistance in the surrounding ecoregions. A more detailed evaluation
of Coral Triangle and non-Coral Triangle sites found higher resistance to thermal stress within the Coral Triangle, associated with c. 2.5 times more recent historical
thermal anomalies and more centralized, warmer, and cool-water skew SST distributions,
than in non-Coral Triangle sites. Our findings identify the importance of environmental
history and geographic context in future predictions of bleaching, and
identify some potential drivers of coral resistance to thermal stress.
Main conclusions: Simple threshold models of heat stress and coral acclimation are
commonly used to predict the future of coral reefs. Here and elsewhere we show that
large-scale responses of coral communities to heat stress are geographically variable
and associated with differential environmental stresses and histories.
